To all whom itmay concern:

Be it known that I, RALPH 1. 'in'r'rne, a citizen of the United States,residing at Arrochar, Staten Island, 'in the county of Richmond andState of New York, have invented certain new and useful Improve ments inRailway-Traffic-Contrailling Apparatus, of which the following is aspecification.

My invention relates to apparatus for eontrolling railway cars or trainsor for giving a signal aboar a car or train.

I will describe one form of apparatus emhodying my invention, and willthen point out the novel features thereof in claims.

.- In the accompanying drawings, Figure 1 a View showing in transversesection a portion of a railway car or vehicle having applied thereto oneform of apparatus embodying my invention. Fig. 2 is a view showin r inside elevation the apparatus shown in Fig. 1.. Fig. 3 is a view showingin perspective a portion of the apparatus shown in Figs. 1 and 2. Fig. iis a diagrammatic r a trip 3, the ends of which, here shown,

are inclined. Mounted on the car :2 is a shoe 5 adapted to at all timesengage the trip 3 and to he raised by one inclined surface or the otherof the trip according to the direc tion in which the car is moving. Ashere shown the shoe 5 issuspended by two links 16 and 17 pivotallymounted on beams 7, '7 respectively on the car. The shoe 5 is providedat substantially its middle point with a slot 18 in which is pinned thelower end of a rod 9 which extends upwardly through suitable holes in abracket 8 fixed on a beam 10. wardly to the lowest point of their strokeby gravity and by a spring 1:2'the upper end of'which ahuts against theupper arm of bracket 8 and the lower end of which reduced portion of therod 9.

Similar reference characters refer tosirni- The rod 9 and shoe 5 arebiased downspring 12 is constantly un r compression, so that the shoe 5is held down with considerable force; the downward movement of the shoeis limited by the engagement of the collar 19 with the lower arm ofbracket 8.

Mounted on the car in suitable bearings 21, 23, 2'2 and 31 are twotransverse shafts 15 and 2-10. The outer end of shaft 15 is operativelyconnected with the rod 1') by a crank 14. As here shown, this crank 14is clamped to a square im'tionof shaft 15 and is provided with a sfot 28which fits over a It will be seen, therefore, that when the shoe 5 israised by a trip 3, the shaft 15 will he oscillated through a small areof a circle.

The two shafts 15 and 30 are coaxially mounted and terminate at theiradjacent ends in two enlarged portions 24 and 2-3, resrwctively, whichform two members; of an electrounagnelic clutch device C by means ofwhich the shafts may at times he locked together? so that when eithershaft is oscillated the other shaft is oscillated also. The clutch l isprovided with a winding having two sections 26 and-27.

The two hearings 21 and 22 are extended and so shaped as to form .guidesfor two longitudinally movahlc plates 32 and 33. (See Fig. 3 as well aspreceding views.) 'l'ln-se plates rest on a surface 21 formed integralwith the guide 21, and a e held from rising from this surface by twofingers 22 and 22" formed integral with guide 22. One end of plate 32 isprovided with a hole 32 through which passes freely a pin 34 fixed inthe top of clutch member 25, and the adjacent end of plate is providedwith a similar hole 3 through which passes freely a pin 35 fixed in theclutch 'rnemher 24. Hence, it will he seen that when either or both ofthe shafts 15 or 30 are oscillated either one of both of the plates 39.or 33 will he rcciprin-atcd iii their guides.

Plate 32 is biased to the position in which it is shown by a spring 12similar to the spring 12. Spring 1). acts upon a bracket 8 and upon acollar 19 fixed to a rod 9", which rod is connected with shaft :10 by acrank 14 similar to crank 14.

ilalc 32 is adapted to have longitudinal movement only, but plate isadapted to have hoth longitudinal and lateral moveabuts against a collar19 fixed to rod 9. The

when the two plates taneously,

ment of plate33, these plates are constructed as follows Plate 33 isprovided, in its edge which lies adjacent plate 32, with a recess 36having inclined faces, and plate 32 is provided with a rejection 37 thecontour of which matches tliat of recess 36. Hence,

are reciprocated simulplate 33 will not be moved later ally, but wheneither plate is moved longitudinally with. relation to the other theprojection 37 will engage one face or the other of recess 36 and causelateral movement of plate 33 outwardly from plate 32. Plate 33 isbiasedto position parallel with and in engagement with plate 32 y springs 38and 39 mounted on a suitable support 40 and bearing on the plate 33. Thesupport 40 is mountedon the surface 21 Plate 33 is the only one of thetwo plates which is operatively connected at all tlmes with shaft 15,and this plate is reciprocated with each movement of shoe 5. Plate 32 isoperativcly is energized. As 'will hereinafter :appear, however, bothplates 32 and 33 may be provided with mechanical connections by whichthey are moved by exterior means atdifferent times, if desired.

In the form of apparatus shown in Figs; 1 to 3, the clutch C whenenergized, acts as a means for locking shafts 15 and 30 tomoved whenslice 5 is moved. I donot wish to limit myself to the particular form ofelectromagnetic clutch shown in the drawings; any other suitableelectrically controlled device for locking the shafts 15 and The lateralmovement of plate/33 may be employed to govern the vehicle in any de-.sii'ed manner, such as by giving a signal aboard the vehicle 'or bycausing the prog ress of the vehicle to be retarded, or both.

understood that these in any other desired manner. This valve device ispreferably so designed'that when opened it will remain open until thecar is brought to a stop; several forms" of' valve device of this typeare well known in the art.

The electromagnetic clutch C may be coni trolled from an outside sourceby any suitable means. As here shown, current is supplied to thewindings of this clutch by a contact rail 4 located in the trackwayadjacent the trip 3, which rail is engaged by a con 1 of bracket 8 andthe other end of which abuts against a collar 20.fixed on rod 1}. Forconvenience of illustration, I have in the drawing shown the shoe 6 inthe raised position, that is, in the position which it 00- cupies whileriding on rail 4. The down ward movement of the shoe 6 is limited by-.'theengagement of collar 20 with the lower arm of bracket 8; or by theengagement of anut '41 screwed o'n rod 11 with the upper arm of bracket8. As here shown, the contact shoe 6 is electrically connected with rod9 by a wire 42, rod 9 nected with crank 14 by a wire 46, (see Fig. 2),one terminal of clutch winding 27 is connected with shaft 15 by a wire43, the 27 are connect ed.by a Wire 44, and clutch winding 26 isconnected with axle beams 10 and 10 are of insulating material,- as isalso the beam 51 on which bearings 21 and 22 are mounted. Valvedevice 41is also insulated from the brake system. Hence, it

will be seen that the circuit for clutch windings 27 and 26.is insulatedfrom the car Referring no to Fig. 4, I have here shown one method.dfapplfying the apparatusshown in Fig. 1 to one ,orm of signaling InFig. 4 I have shown a stretch of railway track divided by insulatedrailjoints into a plurality of sucxcssive block sections is electricallycon- 2 by a wire 45.

Traffic. through block sections D, C, and B, is gov-.erned by similar signals S", S and S re: spectively. In the form ofsignaling system here shown, when a car or'train occupies one blocksection, the signal for that block section indicates danger, the signalfor the preceding block section. also indicates danger, and the signalfor the second block section inthc rear indicates caution. I have.omitted from the drawing signals for well known and form no part ofmyinveution andwouldunnecessarily complicate the drawing if shown.Located adjacent each signal is a trip 3 each of which may be similar tothe trip 3 shown in Fig. 1.
